Designed by John Browning himself, the Auto-5 was the first successful semi-automatic shotgun ever produced. The A-5 features a distinctive high rear-end, earning it the nickname "Humpback." The top of the action goes straight back on a level with the barrel before cutting down sharply towards the buttstock. The A-5's unique adjustable friction ring set helps control the amount of recoil and the full choke ensures a tight pellet spread. The Ducks Unlimited Edition of the Sweet Sixteen has a high-gloss, high-grade walnut stock with fancy checkering and an exquisitely engraved receiver and trigger gaurd. This shotgun has never been fired. The gun comes with a Modified Invector choke tubes and a Ducks Unlimited hard case. Its wood, metal, and bore are all in excellent condition.
